Used EDWARDS E2M1 #9189994 for sale

EDWARDS E2M1 Vacuum pump is a powerful and economical centrifugal type pump designed for low to medium vacuum requirements. This pump is ideally suited to small industrial or laboratory applications, such as freeze-drying, vacuum distillation and process control. E2M1 is a compact, lightweight, quiet running, rotary displacement-type vacuum pump. Its integrated drive motor is brushless and capable of reaching speeds of up to 17,000 rpm. EDWARDS E2M1 employs two stages of differentially configured impellers that are counter-rotating to build up a vacuum pressure of 0.2 mbar in a discharged atmosphere. For airfree operation, the inner impeller has an externally adjustable bypass port that allows decompression of the air exhausted from the pumping chamber at approximately atmospheric pressure. In order to ensure efficient operation, E2M1 features reliable pumping and thermal protection systems. The inlet and discharge regulating valves enable precise adjustment of the pumping speed depending on the required vacuum level. The pump also has a separate oil circulation system for lubricating the moving parts and a separate thermostatic pressure switch that can detect an excessive temperature rise in the motor windings. Additionally, an electromagnetic safety switch will cut off power supply to the pump in the event of an unexpected electrical power supply surge or an excessive temperature rise. EDWARDS E2M1 is equipped with an asynchronous externally ventilated motor pre-connected to a four-pole, low-noise, three-phase power supply. To ensure easy maintenance, this pump comes with a lube port, oil sight glass, and central auto-drain for oil separation. When compared to conventional rotary pumps, the capacity of E2M1 increases by up to 80%. This pump also has a relatively low amount of vibration, which contributes to longer pump life and improved safety. EDWARDS E2M1 is a reliable, economical, and robust vacuum pump with a wide variety of applications. This pump offers a reliable, non-pulsating and low noise operation with a relatively compact design. With robust construction and a durable design, E2M1 is the ideal choice for small-scale industrial or laboratory applications that require a reliable and low maintenance vacuum pump.
